Answer:
a. 24.5 $
b. 10.5 $
c. 7/10
Step-by-step explanation:
Given the original price of the sweater is: $ 35.
a) If you pay only [tex]$ \frac{7}{10} $[/tex] of the price, then the actual amount paid is: [tex]$ \frac{7}{10} \times 35 = \frac{49}{2} $[/tex] = 24.5 $.
b) Total amount Saved = Actual price - Price you paid
[tex]$ \implies $[/tex] Total Amount Saved = [tex]$ 35 - \frac{49}{2} $[/tex]
[tex]$ = \frac{21}{2} $[/tex] = 10.5 $.
c) Fraction of the original price saved = Total amount Spent/Actual Price
[tex]$ \implies $[/tex] Total amount Saved = [tex]$ \frac{49}{2(35)} $[/tex]
[tex]$ = \frac{49}{70} $[/tex] = [tex]$ \frac{7}{10} $[/tex]
